Abstract (en)
A switch comprising: a channel path comprising a first and a second MOS transistor with common source and gate terminals, and drain terminals defining first and second terminals of the channel path; and control circuitry comprising: a third MOS transistor comprising: a gate coupled to the common source terminal; a source coupled to the common gate terminal by a resistor; and a drain coupled to a first reference terminal; a Zener diode coupled between the gate and source of the third MOS transistor; a first current source, for providing a first current, coupled between the first reference terminal and the common gate terminal; a second current source, for providing a second current greater than the first current, coupled between the source of the third MOS transistor and a second reference terminal; and a switching arrangement configured to selectively enable and disable the first and second current sources.
